TECHNICAL FIELD

This disclosure generally relates to field of corrective shoes and moreparticularly to adjustable corrective shoe components.

BACKGROUND

The approaches described in this section could be pursued but are notnecessarily approaches that have been previously conceived or pursued.Therefore, unless otherwise indicated herein, the approaches describedin this section are not prior art to the claims in this application andare not admitted to be prior art by inclusion in this section.

Pronation and supination are natural movements of a foot when the footabsorbs and reflects ground forces. A challenge may develop when thereare specific excessive deviations in the amount of these naturalmovements in the foot. There is no a perfect presentation for the foot.Every human has a pattern of movement defined by genetics, bodydevelopment, or developmental disabilities. The human body accommodatesfor these deviations but often not without challenges to human gait. Thechallenges may cause pain, imbalance, or soft tissue disturbances in thefoot structure and up in a kinetic chain. People are often unaware thattheir feet are still developing until the age of 14-16 years and thatcorrection of feet can be influenced by many factors. Therefore, thereis great neglect in the management of human feet from the early years ofhuman growth which can grow into permanent developmental challenges.

Solution to correction of the foot is often an arduous scenario of stepsto provide necessary treatment for foot correction. These steps arefurther complicated by high costs of treatment and health providerrequirements for approving the treatment. Today, many people do notobtain treatment due to high costs, are treated over aggressively, orneglect accommodation due to the discomfort of current availableremedies.

To get treatment, the individual or his caregiver faces a two-stepprocess. The first step is an evaluation by a medical professional whereoften a custom device is ordered that implements corrections to the footby adding lifts, wedges, or plastic that is placed to the underside ofor around the foot. The second step is buying shoes into which thecustomer devices will be inserted. Such treatment is costly and timeconsuming due to the requirement for follow ups and modifications overwear time.

Medical coverage is changing. Insurance, Medicare, and Medicaid programsare greatly reduced as deductibles rise. Thus, there is a need for adevice that may be purchased substantially off the shelf and requireminimal customization, and yet is adjustable accommodation for necessaryfoot correction and protection for individuals in routine lifeactivities, sport activities, and gait disabilities in every age group.

The following detailed description of embodiments includes references tothe accompanying drawings, which form a part of the detaileddescription. Approaches described in this section are not prior art tothe claims and are not admitted to be prior art by inclusion in thissection. The drawings show illustrations in accordance with exampleembodiments. These example embodiments, which are also referred toherein as “examples,” are described in enough detail to enable thoseskilled in the art to practice the present subject matter. Theembodiments can be combined, other embodiments can be utilized, orstructural, logical and operational changes can be made withoutdeparting from the scope of what is claimed. The following detaileddescription is, therefore, not to be taken in a limiting sense, and thescope is defined by the appended claims and their equivalents.

Generally, the embodiments of this disclosure are concerned withadjustable corrective shoe inserts or components. Some embodiments ofthe present disclosure may provide adjustable corrective shoe componentsto be disposed within shoes.

An example adjustable corrective shoe component may include a correctiverestraint type shell with track cutting, anchors, reliefs, anddirectional pull supports. The shell may include three parts for supportof a foot. The first part is a toe medial or lateral adjustable toestrap. The second part is a sliding adjustable stretch strap to supportthe medial or lateral side of the foot. The third part is a trackedstirrup type strap that protects heel movement. The shell may be securedin the inner lining of a shoe to eliminate migration and shearingmovement of the foot in the shoe. The shell may be made of acompressive, flexible, or semi firm type material that offers dynamicmovement in each section of the foot. The shell may include a moderatelyfirm dynamic skeletal shoe structure that allows unlimited adjustabilityto the medial and lateral forefoot and medial longitudinal arch, andposterior medial and lateral calcaneal wall support with an excavatedheel to biomechanically control heel eversion and inversion.

The adjustable corrective shoe component may include a fore footadjusting pull strap attached to the shell. The pull strap may include astretch material. The pull strap may be attached anywhere along theunderside midsection, lateral, or medial side of the structure at thefore foot and can be stitched, glued, or otherwise secured. The pullstrap forms a pull system that may be pulled over the top of the footover or under the shoe tongue in the direction of the outside of thefoot wall over the outside of the shoe into a loop, d-ring, or strapeyelet integrated into the shoe and pulled back to attach on the upperpart of the strap with a securing yet adjustable type of material suchas hook and loop.

The adjustable corrective shoe component may further include amid-section adjustable pull strap. The mid-section adjustable pull strapmay be made of a stretch material and may be attached anywhere along theunderside midsection, lateral, or medial side of the shell at themidfoot and can be stitched, glued, or accessory secured. Themid-section adjustable pull strap forms a pull system that may pulledover the top of the foot over or under the shoe tongue in the directionof the outside of the foot wall over the outside of the shoe into aloop, d-ring, or integrated strap eyelet into the shoe and is pulledback to attach on the upper part of the strap with a securing yetadjustable type of material such as hook and loop.

The shell may include various notches along the outer walls (medial,lateral, posterior). The shell may include a firm medial wall. The shellmay include a “Sustentaculum Tali” break that supports the adjustabilityof the medial arch and gives the ability to accommodate the amount ofsupport needed per individual, which may eliminate the need for anelevated intrinsic/extrinsic arch post. The shell may allow for multipleconfigurations and options on the outer shoe wall for total footmanipulation to accommodate various foot deviations.

The shell may include a “U” cutout in a hind section to accommodate aheel. The inner wall of the shell may include a posterior medial andlateral Achilles pillow to support a heel clasp. The adjustable shoecomponent may include straps attached to the shell above the “U” cutout.The straps may be pulled out of the back or side counter of the shoe andsecured by pulling the strap on the outside of the medial and lateralside of the shoe counter with a hook and loop type material or pulledout and secured with a cord stop type accessory.

The shell may further include a lightweight, flexible, vertebrae sole.The sole may work in conjunction with pull straps attached to the wallof the shell to adjust the desired direction needed in fore-footdeviation in any foot structure. Thus, the shell and the straps attachedto the wall of the shell may provide a three part adjustable control tothe foot structure: fore-foot, midfoot, and hind-foot.

The adjustable corrective shoe component may be manufactured in volumeand offered at economical prices so that an individual may purchase theadjustable corrective shoe component without having to be concerned withinsurance coverage and costs. The individual may not need to visit aprofessional for custom adjustments of the adjustable corrective shoecomponent, as adjustments can be accommodated at home to providestabilization during an individual's changing gait needs.

Additionally, the adjustivecorrective shoe component 300 may include a second toe strap 320attached at bottom of a lateral side of forefoot section of the shell310 and a second navicular strap 330 attached at bottom of a lateralside of the middle section of the shell 310.

FIG. 4 is a lateral elevated view of a left shoe 400, according to oneexample embodiment. FIG. 5 is a medial elevated view of the left shoe400. FIG. 6 is a top view of the left shoe 400. FIG. 7 is a backelevated view of the left shoe 400. The adjustable corrective shoecomponent 100 can be installed in the left shoe 400.

The toe strap 140 may be pulled out over the top of the foot or shoetongue in the direction of the outside of the medial side of the footwall over the outside of the shoe and into a d-ring 410 (shown in FIG.4) attached to the shoe 400 and then can be pulled back to attach on anupper part of the toe strap 140 with a securing yet adjustable type offastener, such as a hook-and-loop fastener. For example, a VELCRO®hook-and-loop fastener or similar can be used. In some otherembodiments, the toe strap 140 can be pulled into a loop attached to theshoe 400 or an eyelet integrated in the shoe 400. When pulled up andover the shoe tongue and the foot, the toe strap 140 allows a medialwall of the forefoot section of the shell 110 to conform or correctalignment to a toe area of a foot. The purpose of alignment of theforefoot section of the shell 110 to the foot is to control and orcorrect the metatarsal heads and toes during foot movements, such asforefoot abduction, inversion, eversion, pronation, and supination. Inother embodiments, laces attached to the walls of the forefoot sectionof the shell 110 can be used. The laces may come through or exit theshoe and can be tightened in many ways, such as such as crisscrossed,folded back onto themselves, or coming through the bottom of the shoe upthat is opposite of the sole or shell. The laces can be tightened with abolt style that can be turned in either direction with a knob, dial, ortool type device.

The navicular strap 145 of the adjustable corrective component 100 maybe pulled out over the top of the foot and over or under the shoe tonguein the direction of the outside of the medial side of the foot over theoutside of the shoe and into a d-ring 420 attached to lateral side ofthe shoe.

The navicular strap 145, when pulled up and over, mayallow the inside wall of the mid-section 120 to conform to an arch of afoot. The shell 110 can be made from materials that are semi firm andflexible enough to support and compress against the arch.

In some embodiments, the shell 110 can be made of several layers ofmaterials that allow for semi firm and flexible compressions of aspecific arch cut in the shell. The cut may begin at the top of theshell and travel down to the middle of the medial surface or bottom ofthe shell 110. When the shell 110 touches the foot, the arch cut islocated on the medial aspect of the foot, specifically the SustentaculimTali area (known in the field of orthotics as a ST dig) that separatesthe midfoot from the hind foot just beyond the end of the foot arch.When the navicular strap 145 is pulled up and the mid-section 120conforms to the foot, the arch cut separates and creates a movingfloating arch to accommodate any individual's arch height needs. Theshell 110 can be made of materials semi firm and flexible enough tosupport and compress against the arch when pulled in the correctedposition.

The outsole of the shoe 400 may have a slit 430. An accessory strap maybe added permanently or optionally to figure-8 wrap the ankle and attachto the outer sides of the shoe 400 using a hook and loop fastener,d-ring type loop, or eyelet integrated in the shoe.

The first heel strap 155 attached to the medial side of the hind sectionof the shell 110 and the second heel strap 160 attached to the lateralside of the hind section of the shell 110 can be crisscrossed within theshoe. The first heel strap 155 can exit out of the shoe heel counter (orback) and be locked at the lateral side of a shoe using, for example, ahook-and-loop fastener. The second heel strap 160 can exit out of theshoe heel counter (or back) and be locked at the medial side of the shoeusing, for example, a hook-and-loop fastener. The first heel strap 155and the second heel strap 160 can be used to compress and secure thehind section of the shell 110 to the heel of the foot. In some otherembodiments, the first heel strap 155 and the second heel strap 160 canbe locked at the back of the shoe with a cord stop lock. In someembodiments, the shoe 400 may include an inner pocket design 195 of FIG.7 within the shoe wall or outside of the shoe heel wall to place strapsand the cord stop lock.
